Geology, biology, botany, volcanology, paleontology....the list of subjects for scientific study in Lake Clark National Park and Preserve is nearly endless. Coastal cliffs on Cook Inlet hold fossil remnants of 150 million years of sea life. Below them, salmon pass through tidal estuaries on their way to spawning grounds in mountain lakes, chased by hungry seals and brown bears. Two active volcanoes – Mt. Iliamna and Mt. Redoubt – tower above the landscape. Glaciers wind their way down into valleys where the Alaska and Aleutian ranges join. Dall sheep share treacherous mountain slopes with delicate alpine wildflowers. Continuously inhabited since early prehistoric times, the Lake Clark region nevertheless remains sparsely populated by humans. Follow the links above to learn more about this wild, complex place.
